In the same way, Abraham "believed God, and it was credited to him as righteousness."

You see, then, that those who have faith are Abraham's real descendants.

Because the Scripture saw ahead of time that God would justify the gentiles by faith, it announced the gospel to Abraham beforehand when it said, "Through you all nations will be blessed."

Therefore, those who believe are blessed together with Abraham, the one who believed.

This happened in order that the blessing promised to Abraham would come to the gentiles through the Messiah Jesus, so that we might receive the promised Spirit through faith.

Now the promises were spoken to Abraham and to his descendant. It doesn't say "descendants," referring to many, but "your descendant," referring to one person, who is the Messiah.

For if the inheritance comes about through the Law, it no longer comes about through the promise. But it was through a promise that God so graciously gave it to Abraham.

And if you belong to the Messiah, then you are Abraham's descendants indeed, and heirs according to the promise.

For it is written that Abraham had two sons, one by a slave woman and the other by a free woman.
